Having everyone vote modes is too complicated and dumb. Blue should be Game Host and should stay this way. If your not hosting on a bot and you use a normal host to play the game. People would find ways to abuse this and be stupid with the rune voting and such or "mode" voting.

Not that I would support it but if you were going to implement a vote at the beginning for -nr, you'd have to make sure the voting time is done before they even show your -sd heroes. Because some heroes can use runes better than others, you're more likely to vote yes/no based on that.
